"Oh, suck it, Rachel!" Dr. Mitchell panted, early the next morning. "Oh, make it cum, honey! We've got to hurry! Make it cum!"
There was a patient outside, Rachel knew. She didn't even know the guys name. He was there for a teeth-cleaning, and the appointment was with her, specifically. Dr. Patterson was busy, and – at least if her cocksucking had it's usual effects – Dr. Mitchell would be in no shape to service anyone for another quarter of an hour, at the very least.
Oooh, she just loved sucking his huge boner so much! Dr. Mitchell was now sprawled on the couch where they'd fucked the day before, with his pants hastily pulled open and bunched around his knees. They didn't have time for a full-blown fuck session. Actually, they both knew they didn't have time for sex activity at all.
She just couldn't resist him, though. It was that simple. They'd been in the office together, and she'd noticed him ogling her body, and then she'd seen his crotch bulging. It had been a simple matter to giggle and lean in close to rub his big, meaty dick for him.
And now she was sucking it. Rachel had her hand wrapped around the shaft again, and was furiously pumping the meat with her fist. Her lips were stretched open as wide as possible, wetly enveloping the blue-veined shaft. Hungrily the cock-starved teen bobbed her face on his crotch, puckering and puffing her cheeks, slurping noisily on the blood-beating stiffness of his fuck meat.
"Gonna cum!" the dentist groaned. He held Rachel's head with both hands, his spit-basted rod throbbing wildly in her mouth, thrusting his hips off the couch. "Suck it, Rachel! Make it cum, honey! Oh, I'm getting close! Really need to cum!"
Rachel sucked the big pisser as hard as she could, caving in her cheeks even more sharply, her whole face reddening with the torrid intensity of her cocksucking. Her hand was a blur now, whipping up and down the stiff shaft.
Dr. Mitchell sighed as the milky white goo started flooding out of the head of his dick.
"Ahhhhh! Yes, Rachel! Ahhhhhh!" The hot jizz gushed out in long, lashing spouts, raining on the roof of her mouth, flooding her throat with the erupting profusion of his jizz. Rachel clung to the monster prick, jacking and sucking. Hungrily she kept slurping on his prick until she'd milked the last droplets out of the knob of his meat.
"Oh, that was good!" the dentist moaned and slumped heavily on the couch.
"Oh, shit, look at the time!" Rachel cried. "I gotta get out there!"
The busty dental assistant sat back on her heels, her eyes widening as she looked at the clock. She was ten minutes late! They didn't have that big a customer base as it was, and if she fucked this one up…
Rachel rushed out of the room, slamming the door behind her. She found the patient waiting on the big dental chair in one of the examination rooms. He'd already tucked the bib under his collar, and looked only slightly annoyed.
"I'm sorry to keep you waiting, Sir," Rachel started to say, but the words came out poorly. This was because she still had a lot of dick juice mooshing around on her tongue. She hoped the white stuff didn't show.
"Oh, shit, yes, get my little asshole all juicy!" Rachel panted, at five-thirty that afternoon. "Oh, fuck, it feels all swollen and tingly! I really need a good butt fucking bad today, Dr. Mitchell! Umgggggh! Keep juicing up my asshole, Sir! Fuck my butt, fuck my horny little butthole!"
Rachel was crouched on her knees now, completely naked, still on the rich shag carpet of Dr. Mitchell's office. She had her arms up behind her back, and was shamelessly holding her rounded asscheeks spread open as far as she could.
This time, now that the work day was concluded, Dr. Mitchell had also taken the time to remove all of his clothes. His huge prick twitched up and down as he knelt behind her, holding a big jar of petroleum jelly in his hands.
Eagerly he dipped his fingers into the jar, withdrawing more of the lube. Then he started massaging it on Rachel's itchy little asshole again, watching the pink, puckered shit sphincter throb in and out as he darted his finger into her rubbery shitter.
"That's enough!" Rachel gasped. "Oh, shit, my assholes so fucking horny today! I need butt fucking really bad! Fuck my asshole, Dr. Mitchell! Hurry, hurry, my asshole needs your big dick!"
Dr. Mitchell dipped his fingers back into the jar one more time, thoroughly slickening his immense, jutting hard-on with more of the goo. Then he mounted the teenager, aiming his fat, oozing cockhead at her invitingly distended shit sphincter.
Rachel grimaced as she felt the meat pole going in, spreading her asshole to the bursting point around the invading thickness of his cock. Fortunately, he'd greased up her little anus very well – her asshole was spreading wide, but there was no pain as her rubbery ass channel accommodated his bowel-rooting prick.
"Fuck my butt good, Dr. Mitchell!" Rachel sprawled low on her knees, still holding her asscheeks spread open with her fingers. Eagerly she started humping to meet his thrusts, wiggling her buns to help him shove all of his cock deep into her bowels.
"Unh, you've got such a big one, Doctor! Oh, fuck, it's going up my asshole now! Unnggggh! It's going in really deep! Fuck my little asshole, Dr. Mitchell! Oh, shit, oh, please, my asshole needs your big dick!"
Dr. Mitchell grunted, coming down hard, spearing his huge cock much harder into the sucking tightness of her bowels. Suddenly it was all the way inside her, buried to the balls in the rubbery, shaft-gripping tightness of her shitter.
Rachel stopped trying to hold her buns spread open. It was no longer necessary, now that he had her butthole utterly stuffed with hard meat. She sprawled flat on the floor, quickly thrusting her hands under her belly. Then the naked teen shamelessly started fingerfucking herself, thrusting her fingers in and out of her wet little pussy as her asshole spasmed uncontrollably around the satisfying stiffness of his cock.
"Fuck my asshole!" she pleaded, in a home, almost miserable-sounding voice. "Awwwww, fuck my asshole, fuck my horny asshole!"
The dentist pulled out slowly, withdrawing until only the knob of his hard-on distended her swollen, tingly shit sphincter. He paused, then sank his grease-lubed cock back into her asshole.
Rachel gasped with pleasure, fingerfucking her pussy and thrusting her burning asshole onto his cock as hard as she could. Soon the hung, handsome dentist had settled into a good, hard, shithole-reaming rhythm. In and out his big cock pumped, stabbing in and out of her asshole, satisfying the narrow, gripping tunnel with every thrust of his prick.
"Unh, I love it, oh, shit, I need it so bad!" Rachel panted hoarsely. "Unngggh! My asshole loves your big dick, Dr. Mitchell! Oh, shit, fuck it harder! Unh, fuck my horny little asshole just as hard as you can!"
Dr. Mitchell panted on her shoulder, his giant cock nursed to total stiffness by the gripping, enveloping warmth of her bowel tract. Soon he had thrown away the last shreds of restraint, and he was hammering his huge prick in and out of her red, distended asshole just as hard as he could.
"Yes, oh, yes!" Rachel gasped. She fingerfucked in a frenzy, grimacing and moaning as the indescribable beat of butthole-reaming built in her bowels. "Love it so much, Sir! Unh unh unh, fuck my asshole, fuck my horny little asshole! Need to cum now! Oh, shit, I'm cumming, my assholes cuuummniilinnnggg!"
Her tender asshole erupted in violent orgasm, flexing around the root of his prick, the rubbery channel gripping and squeezing the stiff pisser again and again. Dr. Mitchell moaned, collapsing on top of her, ramming his cock as far up her stretched little asshole as it would go.
The milky white prick-juice spewed out of his cock, squirting and spraying torrentially into the sucking heat of her bowels. A wanton, shameless smile of total sexual contentment spread across Rachel's face as she felt her itchy asshole flooded with the soothing juices of his cum.
"Oh, Doctor!" Hornily she wiggled and thrust beneath him, flexing her shitting muscles, making her tight little asshole suck out all of the jizz.
"I should have known!"
The loud, angry voice was from the now-open door to the office. Rachel looked up.
It was Dr. Rob Patterson. He was staring down at them, with a jealous, angry expression on his face, and a very conspicuous-looking hard-on tenting through the crotch of his black dress slacks.
